SPECIFICATION forming part of Letters Patent No. 585,803, dated July 6, 1897". Application led May 19, 1896. Serial No. 592,217. (No model.)

To ali whom it mail concern.-

Be itknown that I, EDWARD P. WAGGONER, of Syracuse, in the county of Onondaga, in the State of New York,have invented new and useful Improvements in Generators, of which the following,taken in connection with the accom# bled, facilitates a positive and rapid circulation of the heatingiiuid, is durable and effective in use; and to this end it consists, cssentially, in the general construction and arrangement of the componentparts of the generator, all as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figures l and 2 are respectively front and rear perspectives of my improved generator. Fig. 3 is a longitudinal vertical section taken on line 3 3, Fig. l. Fig. Z lisaperspective illustrating the detached upright sections of my generator as somewhat separated. Fig. 5 is a perspective of the detached base of my genn erator, and Figs. 6 and 7- are perspectives of modiiied forms of my generator.

A AA2 A3 A4 are a `series of upright sections arranged one in advance of the other for forming the main body of the generator.

B is a base upon which said sections are mounted.

C D are chambers secured, respectively, to the front and rear walls of the sections A A4,

and E F are suitable inlet and outlet liuid-` portions, and the outer faces of the top and bottom walls of a number of said sections are substantially smooth and continuous or unbroken'. The outer faces of the lower extremities vof the upright sections are usually provided with shoulders s, extending lengthwise of the generator, for engaging the base B, presently described. The front and rear walls of the sections A A A2 A3 A4, which -may be provided with interlocking tongues and grooves a a', are formed substantially fiat, and are rmly secured together by bolts A5, passed through said sections and connections or tubes, presently described, for connectiug said sections. The upper and lower portions of said front and rear walls preferably decrease in width toward their top and bottom edges, which are usually rounding.

The sections AA A? A3 A4 are provided with substantially centrally-arranged upper and lower fluid-openings d2 d3 in their front and rear walls, which form water-passages extending lengthwise of the generator, facilitate a circulation in the generator, and are usually formed, respectively, in substantially the uppermost and lowermost portions of the extremities of said sections when formed as justdescribed. Oonsequentlythe tluid-cham bers in said sections, which duid-chambers form the heating-chamber of the generator, extend downwardly and outwardly from the openings 01.2 and upwardly and outwardly from the openings a3. upper and lower openings a2 a3 of adjacent upright sections of my generator are connected together by any suitable means and preferably by short tubes or pipes Gr, having their opposite ends suitably fixed or secured within said openings. Sections of this construction are readily handled, owing to their curved faces, present a large amount of lheating-surface with aminimum weight of The correspondin g IOO seen at Figs. 2 and 3, the top walls of said passages or openings in the lower extremities of the sections A A A2 A2 A4 are provided with lengthwise corrugations a4, which form the top wall of the combustion-chamber A7. The portions of the sections A A A2 A3 A4 forming the bottom and side walls of the ashpit A1 and the side walls of the combustionchamber preferably consist of substantially U-shaped chambers connected together by the openings d2 and opening into the connected fluid-chambers in the upper extremities of said sections. The inner walls of said U -shaped chambers preferably support a suitable grate l-I for separating the ash-pit and the combustion-chamber.

Suitable upper andlower passages or openings extend lengthwise of my improved generator through the duid-chambers in the upper extremities of the sections A A A2 A9 A4, beneath the Huid-openings a2, and the adjacent ends of corresponding passages are alined with each other and arranged in close proximity to each other for forming continuous or closed upper and lower flues A8 A9.

vA fire-passage A10 extends downwardly in the section A4 from the rear end of the lower the front ends of said upper and lower flues are usually connected as presently described.k

As best seen at Fig. 4, the sections A A A2 AASA4 are preferably provided with a number of upper and lower lues A8 A9, and the lower portions of the rear ends of' the flues A9 are cut away for forming a comparatively large chamber, which is provided with a rear outlet-passage a5 and greatly facilitates the passage of the products of combustion from 'the fire-passage A19 into the iiues A9. The lower end of the fire-passage A10 is connected to the upper portion of the rear end of the combustion-chamber A7 by a fire-passage A11, extending through the section A3, which is arranged in front of the section A4 and is provided with a bridge-wall A12, preferably formed hollow and arranged at the rear of the combustionchamber beneath the fire-passage A11. The water-con taining chamber of the rear section A4 preferably extends only a limited distance beneath the nre-passage A19 and the top edge of the bridge-wall A12, and an opening A19 is formed in said section A4 at the rear of the bridge-wall A12 for decreasing the weight of said section. opening A13 may be dispensed with it desired.

The base B, which may consist of a single piece or several sections arranged endto end, extends from front to rear of the generator beneath the sections A A A2 A3 A4, and its upper face has a lengthwise groove therein,

Itis obvious, however, that this I is preferably formed concave, and is provided with separated longitudinal bearing-surfaces b b, inclined downwardly toward each other for engaging the adjacent faces of the lower ends of said sections, which extend downwardly into said lengthwise groove. The chamber C connects the front ends of the tlues A8 A9 and the chamber D connects the rear ends of the iues As and the outlet a5 to adraft conduit or pipe CZ. Suitable dampers d d2may be arranged, respectively, in the chamber D and the conduit el for varying the path and the-draft of the products of combustion.

It will be readily apparent that although the ash-pit of my generator is inclosed, as described, by U-shaped watercontaining chambers at the lower extremities of the upright sections of the generator it may be otherwise formed, if desired. I have therefore illustrated in Fig. 6 a modified construction of my invention in which each section is formed with separated inlet conn ectionsa19, arranged on opposite sides of the base of the combustion-chamber 0.11, and is provided with separable base portions @12, formed' U-shaped in cross-section, which inclose the ash-pit a13'and are suitably secured to the top portions of said sections.

In Fig. 7 I have shown a further modified -form of my invention, in which the ash-pit d20 is inclosed by a common base portion or continuous U-shaped wall a21, arranged beneath sections L22 of similar construction to the upper and central portions of the upright sections of the preferable form of my` invention.

It will also be obvious that Ido not lherein claim a generator composed of upright sections arranged one in advance of the other and provided with a separable base portion formed continuous or in sections, as the same forms thel subject-matter of my pending application, Serial No. 593,473,1iled May 28, 1896; nor do I claim thek construction of the sections A A A2 and the base B of my improved generator, except in combination, as said sections and base form the subjectmatter of my pending applications, Serial Nos. 617,766, 617,768, 617,767, and 617,769, filed January 2, 1897.

The operation of my improved. generator will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be particularly noted that I do not herein specifically limit myself to the exact detail construction and arrangement of its component parts, as the same may obviously be varied without departing from the spirit of my invention.
